“The knowledge about nature is extremely important to develop technology”. Support this statement by giving three examples.

The development of technology leads to the standard of living of people thereby improving the economic development of a country. But the knowledge of nature is very important to develop new technology. This can be well understood from the following points:

a. Man discovered fire after rubbing two pieces of stone. Nature taught him the concept of friction.

b. Many congenital, as well as acquired diseases, are cured by modern science after an in-depth study of the features of genetics.

c. Aeroplanes and helicopters are developed after understanding the laws of aerodynamics.
